Dear friends , I have problem with my account for 2 weeks. In a day my earnings are always reduced . I dont why . For ex. today my earnings was 100$ but after 1-2 hour I saw that it is reduced to $60. It is like that for two weeks , I dont know the reason. I dont think it is about invalid clicks ,everyday $30-40 is a huge amount. There was nothing same before . How can I solve this problem ? Thanks in advance.
That's a huge differential. No idea how you solve that, looks like a massive amount of invalid clicks.
Try and contact Google, perhaps the $100 is just predicted earnings not adjusted for total earnings that day (i.e. the earnings per click was actually lower).
